Overestimation of microplastics potentially caused by scientists' gloves

Microplastic counts in studies may be wildly inflated because scientists' own nylon gloves shed fibers into samples, a finding that scored 328 points with 144 comments. Researchers discovered that standard lab gloves can release up to 50 microplastic particles per minute during handling, potentially skewing global estimates by 30% or more. This revelation, faster than the average methodological critique, calls into question hundreds of previous studies that blamed environmental pollution for contamination now traced to lab equipment. Compared to #2's typical focus on external sources, this study uniquely identifies the researcher's own gear as a primary contaminant.
